wouldn't be my choice of car to be fair, i'd probably keep the ibiza. unless your one of these rich students, cos you would have to be cos older cars always have stuff wanting done to them 
yeah don't i bloody know it.
Right, i'm a student and live on approx £350 a month (but have reasonably generous relatives when i need help) I run a 1990 Gti 8v and am only 19 (was 18 when i took the insurance out so i'm paying £154a month till next month) anyway...i really do struggle to keep it. Since i've had it, i've had to change the interior,replace rear bumper, get an airbox for it, repair the two rear number plate lights, tyres, TAX (a right killer), the clutch is going and it keeps cutting out at the moment. It really is one thing after another, and i weekly consider to sell it, and i may still after i get my insurance renewal through, depending on how much i'll have to pay.
However i do love my car and would be very sad to see it go, so i'm gonna try and keep hold of it and when iget my student loan in September spend a little making her mint!
hope that gives you an idea.
