Been put off the diesels.
I'm off to look at a 1.6 16v Factory LPG Estate..... it'll be the small block VX engine, which I know very well, so makes sense......
Check what make... If it's a Koltec-Necam (which I suspect it will be) knowledge and parts are hard to come by. They also have a stupid in tank pump (LPG), IIRCC, which is prone to going belly up. Not cheap
Personally I'd steer clear of a factory fit (if it's Koltec-Necam) and buy a standard one and pay for a Stag kit for it
I know the Koltec install reasonable well, and have a fair few spare parts for it here.
if it failed, I'd replace with stag, but otherwise I'm impressed with the factory fit LPG'd Vauxhalls.
My (and Taxi Drivers) veccy estate did over 230,000 miles - with a factory fit - and it only went wrong once in that time, not bad really.
I agree though, I've heard of others who have had issues....
