I've had the M6 bug for a while (basically ever since I drove one) and I'm getting closer to buying one.

I can buy it from a BMW dealer and pay a huge premium, or I can buy one from Carvana for slightly less - the advantage with the latter is that you have 7 days to return it. Or I could really be brave and buy one at Manheim (I know a guy...) at wholesale and hopefully come out ahead financially, albeit without any return or even a test drive possibility.

I've owned many BMWs, so I know all about repair costs and unexpected failures. The scary part of a used M car is you don't how much it's been abused or pampered, and these engine failures can be expensive. So I thought, buy the Carvana car, Fedex the oil sample to Blackstone, and if it comes back with any bad signs, take it back for a refund (the car, not the oil).

Presumably they change the oil before they sell the car, so I don't know how accurate the report would be, and it gives me a very small window of opportunity. I am not a fan of extended warranties, so although it's an option as well, it's not one that I particularly want to pursue. I'm sure it's expensive on a F13.

And note that I'm not picking on the M6, as BMW V8 models in the past 8 years have all been somewhat problematic, and the S63 actually less so than the N63.

Thoughts? Advice? Suggestions?
