2010 C63 without warranty, risk it or trade it in?
My 2010 C63's (Canadian, P31 performance package, 60000km) warranty runs out this September. I'm torn between keeping it without warranty and risking the headbolts failing, or trading it in for a newer C63.
1. If I keep it, I'd probably swap out the headbolts for Weistec studs. Rotors might be wearing out soon as well, so might have to replace those.
So ~$3000CAD for parts&labor for the studs, and ~$3000-4000CAD for rotors and pads.
2. Trade in for something newer. Preferably would look for a 2014 507 edition, but that will be hard. Still not a fan of the new C-Class exterior
, but the interior is beautiful.With the Canadian dollar doing so bad, I would like to make a smart move financially but still have fun with a 63
. As for my current C63, I absolutely love it. It's been rock solid since I got it. No changes in coolant levels, and engine normal oil loss (~1L/10000km), but it's in the affected range of the faulty head bolts and in my mind it just seems like a ticking time bomb.Hopefully my fellow 63 owners can help me make a decision
The car is stored for winter at the moment, but once summer comes I plan on driving it very hard until September, at least.Cheers
Also, you don't NEED to put p31 rotors back on your car. If you just drive it on the street you can get standard c63 rotors and will save a TON of money. The standard rotor is still a great performer and slotted, it just isn't two pieces. An OEM two piece is $1833/ea (USD) and a regular rotor is $264 (USD). Those are off ECSTuning which is a great place to shop.
Sounds like you love the car you're in. I'd do the maintenance and keep that car on the road.

Also I know many dealers work with customers on the price of the repair since it's a known issue

You dont NEED to do the headbolts. Yes, people have had issues. However, it really isnt as common as a forum makes it out to be. After all, a lot of people head to forum communities in the first place with complaints or concerns so issues (especially those that can be expensive) tend to be exaggerated some.
I just hate telling PFL owners to not worry at all and then have something bad happen. I'd feel guilty. But at the end of the day, the headbolts aren't as bad as people make them out to be.
You don't need p31 brake rotors (two piece), that is where all the $$ comes from. The one piece rotors are fine, a faction of the price and I guarantee you won't notice a difference.
With 60,000km I can almost guarantee your p31 rotors are fine. I have 93,000km on mine and I still have material left before the wear limit. Dealer or shops just throw these rotors out and sell you new ones instead of just putting new pads on, which is all that is needed. The wear limit is about 3mm and with 60,000km you probably have 1mm of wear. The numbers are stamped on the rotor, just need to measure with a calliper to see where your at.
Shoot me a PM if interested.

Yeah I think they are fine too, I haven't gotten the chance to measuring them since I've been away for a couple months. Lone Star in Calgary said they HAVE to replace rotors when replacing pads (something to do with liability), I don't know if I was just speaking with an idiot or that's their actual policy. If it is the case, that's quite bull****!
Coupe or sedan?
