hi, i have decided to buy an old golf cabriolet as a runaround second car come winter project, i know very little about old golfs so far and would be gratefull if you could advise the pros and cons/ preferences of the various early models and maybe what to look for when buying one. my budget is up to about 2.5k. i have an engineering background and looking forward to owning and working on one, thanks for any help in advance.
