check around the back area of the car were the fabric starts for the roof if rust there walk away fast
Sorry dudes, but if you're afraid of rust or spending money and time fixing (loving) it then you're not cut out to own a mk1.... FUGGEDDABOUDIT! *Italianamericannewyorkstyleaccent*
Fuel filler neck rusts but relatively cheap and easy to fit a new one yourself. BIG ONE: Bottom of rear window frame rust... you can't see this but look for signs 'cos a new window frame is expensive. Best thing to do if you do need a new hood is to get the liner, and rear frame done at the same time as you need to take the outer hood off to fit a new liner and the rear frame (which is always knacked). I got a new hood and put my old crusty window frame back in... still in there rusting away! The back metal lip hydro mentioned (where the roof tension cable runs at the bottom back of the hood) does rust but you can have that sorted easy, it's just a lip that creates a channel for the cable to sit in and is not seen with the hood on. Mine rusted.. just peeled up the hood and took it back to metal and painted it.. voila.
Leaky/knackered roof... nothing £500 worth of rubber seals or roof can't fix though!
Engines are generally solid but pierberg 2b carbs and associated auto choke / non wax stat *black magic vacuum* - they're total dogsh.. replace with a weber for under £100 though.
You're in the wrong place... Get yourself onto here
