Carlton gsi3000 54000 miles 2 owners 1987 E reg

As the title suggests for sale is a carlton 3000gsi, it's in very good original condition with only 54000 miles and all mots to prove, the mot is only short and ill probably put it through for another one as there's nothing I can see that will be a problem, it's in dark grey with half leather interior and drives very well, I'm. Not really sure how much to ask as its quite rare now and in this condition with the mileage to, what's it worth? Can be viewed in evesham Worcestershire pictures to follow
