I'm going to look at an '87 turbo and I was wondering how long it would take for a mazda dealer todo a compression check, would it take awhile?
When I take it for a test drive and test the turbo and everything out should I get on the high way and drive it aggressivly, i.e., redlining it when shifting, but if somthing is wrong with it I dont want to break it.
Anything else?

 

i say go drive it hard on the highway, before you buy it (hence testdrive)
if it breaks, oh well, dont buy it(or get the guy to knock some money off of it) , better it breaks before you buy then after you throw some money down and are driving home.
