i had an absolute minter for about a year, and i've come across quite a few others.

as said rust is a big worry, filler caps usually go (90% of the time)...if there's no rust check for a repair just in case...sills go at the rear, and even in the door shuts, i've seen floors go too.

The engines are sound and tbh i'd stick with a T2 if you only want 180bhp....mine had 228bhp but the poor little thing was being run to it's limit and it was shite at the top end really....but great spool up

T3 is an easy enough conversion though.

the management is a worry IMO, most have superchips fitted, and these are tempremental, and the system on the whole is just a bit 'non user friendly'....ideally you'd change to cossie management, which is fairly simple and inexpensive nowadays.

great looking cars though when mint

any specific questions just ask...i'd be glad to help
