I think you have to ask yourself the question, do I really need another toy that is going to sit in the garage for maybe 360 days a year?
Or have a 126 on the road, taxed and insured for around 250 quid that you can use when ever you want and be the envy of all your friends
You already have a quick euro box and a blitz buggy to play with at weekends
but how many times a year do you load up the trailer and use it?
Only you can make that decision
but as reported on here there are so many 126 projects that come up on Ebay, + you will be hard pressed to get the money/time and effort back that you have put in, where as 126's that are looked after are going up in price
