Increase resale value with adding retrofits/mods?
) I am wondering what retrofits/modifications will increase the resale value of my C230K. I need to get minimum of 10k $$ out of this thing and right now the average resale price in my area is at the 8.5k $$ mark. This is the only C230K Sport sedan in my province that I know of, so province wide rarity will be on my side.I have the following retrofits in mind:
- Finishing the BT phone functionality (still need the BT puck and trunk module, but everything else is there)
- Retrofitting the command Audio/Nav system (I don't know if this will be in conflict with BT compatibility, since the pre-wiring for the BT phone functionality is already in the car
)- Bi-xenon headlamps and auto leveling retrofit (I haven't been able to find any diy's on the auto leveling retrofit, but I have all the info I need for the Bi-xenon bit)
For modifications:
- Making the exhaust a bit more noticeable and better sounding tone (not too loud, just better sound quality and a touch more volume when on the throttle)
- Kleemann Header (this is probably too expensive unless someone has a used one for cheap)
- A smaller S/C pulley or over-sized crank pulley (anyone have one for sale? I can't seem to find one anywhere)
- Deleting the S/C resonator pipe or S/C muffler as some people call it (I have a nice bright blue powder coated aluminum intercooler pipe with all needed t-clamps and silicone couplers to make for a very clean install)
- Either a custom tune or Eurocharged tune (dependent on how far with the engine/supercharger/exhaust mods I decide to go)
- Sprint booster (not a power adder
, but increase in throttle response could add to resale value)- Coil over kit (will be going with an H&R Street coilover set if I go this route)
- Will be buying some offset chrome 18x7 (front) and 18x8 (rear) wheels this fall, as I will be using the Elbrus 18x7 wheels for winter since they have minor scuffs already.
That's everything I had in mind, but I'm open to any additions people might have. Anyone have any ideas how far I will have to go to get past the 10k mark for resale? The new wheels, BT phone functionality, and the S/C resonator delete WILL be happening. But the rest is up in the air until I get a better idea of how close to 10k I will be at after those three. The car has 178,000km on it and zero interior or mechanical issues. But the hood and front bumper is being repainted to repair some rock chips from previous owner
, so I'm trying to get it out in the next two months before something breaks on me. I have attached a pic to spark interest. I went the next province over (800 kms) but only paid 6K for this since the previous owner was in quite a bind financially. That said I need at least 10k for the bimmer I have my eye on, so that's what I'm shooting for.

I use to have a 1994 Honda Civic Si coupe a few years ago. I originally bought it for $3,300 and it was in immaculate shape inside and out. Only had 170,000 km on it and was fully loaded with a 5 speed manual transmission, it was a great base to build off of. Over the next year that I owned it, I threw about $8,000 into it. $3,500 into the suspension and wheels, then another $4,500 into the engine, drive line, and a turbo kit pushing 8 psi. I sold the car a few months later for $9,000. Now, I bought the car for $3,300 and put $8,000 into it; then I sold it for $9,000. I lost about $2,300 in the whole deal, since my total investment was $11,300. But I now had $9,000 in my pocket from the sale of that car.
I started out with $3300 before I bought the car, and ended up with $9000 after I sold it. I'm trying to do the same idea here. I started out with $6,000, but I need to end up with $10,000 or more after selling it.
I know adding wheels and the BT phone functionality will increase the resale value, but I don't know by how much. I'm looking for advice from someone who has modded and sold one of these before.

Even parting out is annoying as there is such a small market for Benz mods. You're better off just leaving it as is, getting what you can, and going back to BMW. I don't blame you, either. Benzes are ho-hum.

. And what is with the switch row above the head unit with sooo many blank spaces? I hate how this car is the "Sport" version, but feels like a base model on the inside. Don't get me wrong, I am quite fond of the handling during spirited driving. And everyone I know has told me this is the best looking car I've ever had. But in my E39, It feels different driving it or even just sitting in it. It doesn't feel cheap or like it's missing alot of features, it feels like a proper German sport sedan. Even the '01 Audi A4 turbo I had before my bimmer felt like a reasonable German sedan (when the check engine light wasn't on of course). Could just be me going from apples to poor quality artificially ripened oranges, I guess. But my MB just isn't cutting it. It's wonderful to look at and handles pretty well, but that's it. Sorry for the rant, but ho-hum is a good way to put it, tommy.

I have been down this road many times and believe me, I have never made money off the mods (unless it was a very unique collector's car).
Best to take the money you would spend on the upgrades and just count it as added value to the sales price.

Not all are awful or ho-hum. But I see why you think that way since you bought a 2002 C230...
The only things I could see adding a touch of resale are xenons, a nice oem style navi and Bluetooth although the cost of them will exceed any raise retail value so keep it stock.
Also your car is blue, probably not a very easy color to sell.
Lastly the E39 is much nicer than a c230. Can't really compare the 2. The E39 is arguably one of the best 5 series ever made I've had a few of them.

Spent $8k to lose $2300.
I'm not sure which facinates me more, you labeling that a success or the idea to do it again.

Considering the OP mods for resale nonsense, I was able to knock a couple grand off the asking price because the shop had made "improvements" to the car. These are high end cars with state of the art tech from the factory - putting anything on the cars that is not original lowers the value. You want faster - get an AMG version.
Usually the "improvements" are there to cover up a break in theft. New wheels, Stereo, even complete front and rear end covers are cheaper than factory originals.
Come on folks, was this guy actually for real?!?
Spend money & time to make less money than if you spent & did nothing?!? I realize theres 7+ Billion of Us on this rock, but no one can be that stupid... can they?!?
