I have one - absolutely no problems with it.
I did go over it with a fine tooth comb . When I got it the oil pump / e-3 exchanger was disabled . Took it off , took it to a radiator shop for cleaning and reinstalled . Everything works fine.
I have looked at several other ones as i was planning on putting another on the road. Every one I looked at needed at least 8 grand or more work on them just to get them up to snuff , not to mention the unknown wear and tear on the engine and transmission .
I basically spent maybe a grand or so on mechanical issues and cosmetics another grand .
Ended up buying a
butler because I couldnt find another in comparable shape as my first one.
One good thing is either blueline or
aerotech still offers support and parts for these models .
