	From 85 onwards pretty much all diesels sold into private hands were 1.6td's, as were factory conversions (Westies) so there are a good few of them around. Service history is the thing to look for. Don't be scared by invoices for new head gaskets / new heads or new turbos ...at least you won't have to do it tomorrow.

	1.7' s are a bit of a mixed bag. You could find one that spent most of its life in a depot and was well cared for by one dedicated driver, or one that was beaten within an inch of its life every working hour by ever changing jockeys on a minimal maintenance budget (ex parcel delivery vans for example) ...trying to ~~guage~~ where it came from and how it was most likely driven can be difficult though and mileage alone isn't really an indicator.		1.7' s are a bit of a mixed bag.

	Poor cold starting in winter can just be broken glo-plugs (cheap fix), blown glo-plug fusible link (even cheaper) - or if persists , very bad sign for engine condition esp. if combined with smoke when warmed up. A good condition TD should start pretty well in warm weather from cold without waiting for glo-plugs, indicating good compressions.
