I echo this. If you are flinching at the cost of just the RACP crack repairs and don't plan on doing it yourself, this is probably not the platform for you. A lot of the enthusiasts here have these cars because they love them or find them special, not particularly because they are a performance or maintenance bargain.

Given that his previous car was a 911, I'd assume yes, really

Lets have a random deep thought.

The E46 M3 has only one serious problem. The rear subframe. It can go as early as 60k miles with normal driving.

Everything else is moot. Rod bearings, trim, leaks, whatever else. It's a high performance car. We could be changing engines multiple times a year like F1, but we're lucky enough that we don't have to do that. For what it is, minus the subframe, I think these cars are built pretty well.

You're info says your in San Diego. In that case your best bet is to take it Kaiv. If you're in Sacramento..never mind.

Some things are more expensive on 911s while others are cheaper. They’re very different cars but no doubt feel more solidly built than an E46 M3 of the same era.

Contemporary (same era) 911 to e46 was 996 (1997-2006)... which has IMS issues nuking the engine, oil starvation on track, difficult to replace coolant lines that cause engine failure, shitty interiors, and LSDs that become open diffs in ~30,000 miles of street use or ~3000 miles of track use. Most jobs on the car are harder to do and the average part costs considerably more.

I'd say subframe mounts and vanos pump disk tabs/lack of lotite on the cam bolts. Other than those, nothing strikes me as exceptional, unreliable, or unusually burdensome.

Yes, the E46 M3 is the only car to own and the best car ever made and must be defended at all costs, we know.


With that said, the IMS issue is pretty much non-existent in 2006-on cars due to the third revision of the IMS bearing. The real issue isn't IMS anyway, it's bore scoring, which typically happens in cars that have lived in colder climates.

Interior in a 997 is way better than an E46 M3, sorry, just the way it is. 996 interiors were pretty bad, but a 996 with full leather is still a nice place to be, wouldn't recommend one without full leather as a C5 Corvette is nicer inside.

As far as LSDs, most cars don't have them anyway as it is an extremely rare option. Traction is not typically an issue in a 911 for obvious reasons.

"same era" (your words) is 996, not 997. Same era is also pre gen 3 IMS. Good that LSDs aren't necessary, since cars that had them quickly didn't
E46s were produced from 1997-2006
996s were produced from 1997-2006

997 started in 2005 so there is some crossover, but typically the 997 does go against the E9x cars as there was more overlap.

Yeah, let's all laugh about the LSDs while we frantically work to replace our rod bearings, vanos units, reinforce our subframes before the floors literally rip apart, have our dangerous airbags replaced, replace our RTABs so our rear tires last longer than 3k miles and the other laundry list of E46 items that need to be addressed on just about every example at this point. indeed.
