Rude to compression test?

What happens if you fuck something up?

I definitely wouldn't allow it. Some random idiot who wants to buy a car for under 5k is going to strip my shit and waste my time.

it's also very easy to fake good compression results by testing it extra wet. Some scrub wants to buy my 3k car that has shit compression in cylinder 2? squirt a bunch of straight 60 into it and I'm golden.

Rather than trying to buy an RX-8 with a working engine, buy one that has a totally dead engine for dirt cheap and replace it at home with a Mazda reman for 3-4 grand. You can spend under 6000 bucks and have a brand new engine, which is really the only major potential trouble spot on a pre-owned RX-8. Bonus points if you get one dead to engine abuse (being babied/overheated/not oil changed) that still has under 50,000 miles on everything else.

but he wont notice the car smoke like a freight train when you start it up?

It's already fucked
