That GTR is no joke.
Mods to get to 600whp ($8K) / Used GT-R ($60K) = 15% of Value
Mods to get to 500whp ($4K) / Used E55 ($25K) = 16% of Value
Mods to get to 500whp ($10K) / Price of Audi S4 ($5K) = 200% of Value
Also, so far the GT-R's value has stayed really strong (probably due to the HUGE price increases on newer models). I bought my car used 2 years ago and could likely sell it for as much I paid while putting 10K miles on it. So for me it doesn't hurt as much putting money into it (as opposed to my old CL65).
as far as the metric you added, you need to add one more factor to make it meaningful....you need to add what you gain for the % of value so normalize the ratio otherwise its not showing anything and would penalize cheaper vehicles like mustangs, and motorcycles...
basically according to you math all i need to to is to have paid more for my audi to reduce the cost of mods as a percent of cost of car

so according to your metric, as long as i paid $66K for my audi then in your formula:
Mods to get to 500whp ($10K) / revised Price of Audi S4 special expensive edition ($66K) = 15% of Value
yeah its a better deal now

$ per HP is really the only way to look at bang for buck.... doesnt always mean is the best kind of HP (as others have noted about NOS), but its still the mathematically correct way.
any ways, i still want some of that $12K change that anyone has laying around in between their sofa cushions and on the floor

With depreciation on cars like that, I usually look at the predecessor model. For instance, if you are looking to buy an Aventador 10 years from now, look at the top-of-the-line Lamborghini model from 10 years ago. That would be a 2002 Murcielago. That model had a list price of $270K before options. Today you can pick one up somewhere north of $120K (assuming clean title and no blemishes on history report). So it retained about 40-50% of its value. With an Aventador's $400K+ price you might still be looking at near $200K for a used one 10 years from now....ouch!

If we raise the bar again and said a 9s run is the goal....there have been full bolt-on E85 tuned GT-Rs that have accomplished that with weight loss (pull seats..etc). That is now in an area where no E55 has run before.
Another issue: it is hard (somewhat unfair) to compare a 10+ year old car....to a 6+ year old car to a 3 year old car price wise. That is especially true because the 3 year old car is theoretically still covered another 2 years under a manufacturer's powertrain warranty which inflates the value (if you can still find a MB CPO'ed E55 it would likely have a premium for that and close the gap on the value discrepancy). Also, the older cars are likely to have a lot more miles on them. You would have to find a GT-R with similar mileage to make an apples to apples comparison. That GT-R would likely fall under $60K. These things mitigate value...but will never overcome the huge discrepancy between cars this far apart in age. I think the better comparison would be to compare cars that were available in the same model year as far as value (ZR1, 997 Turbo, E63, M6, GT500..etc).

293 kW at the wheels in AWD.
I have owned it since 2004.
I service it myself and change the oil every 5K. the only mods are:
Cat back exhaust, Apexi FC with boost control and twin Apexi pods.
Martin Donnon at Willall Racing tuned it and it runs like a watch.
I suppose I could spend another 40K on it and match a 35 but it is plenty fast enough for me.

The next day the owner was driving it and the clutch failed in it and it cost him a big pile of money to fix. He sold it not to long after that because it was always broken and in the shop.

At the end of the day, build quality and reliability-wise, it's still a Nissan.

Having been in this and a few Vette's.....the Nissan has a nicer interior and that ain't saying much.
And you'd have one hell of a hard time arguing the 55 was better in terms of: fun per dollar, repair cost, maintenance cost OR reliability. I've had WAY more problems with my 55 in the same amount of time than my GTR, and that was before modding it. I haven't had a single issue in 15k miles of driving hard in my GTR, including Laguna Seca.
Not going to start a which car is better war... I love them both... I just think maybe having been on both sides of this fence it's obvious by comments who has / has never driven a GTR. No need to bash a car maker's name until you've tasted their best offering.
As for the ZR1, you'd still get smoked 0-60, get far worse gas mileage, live without one of the best AWD systems made, and lose those two rear seats.

Considering for 100k you get something that has the 9th fastest lap of all time at Nurburgring, and considering it's besting cars that cost 2,3,4 and more than 5 times as much... then maybe you'd just never fathom purchasing any of these cars.
I covered my doubts with the mere purchase of an extended warranty.

Just saying... the GT-R has a lot of qualities you need to experience to understand. I do wish they had a super comfort suspension mode. Even the comfort mode makes the 55's sport mode look like marshmellow.

ah yes, the magic airbox! We were very lucky to have been around during those times!
