Are we talking just buying the car? Or can we mod it after purchase?
This TT is £890. With the left over £600 it could be modded up tp 200bhp quite easily. Should pull that car to 60 is ~6 seconds.
Abarth go-kart for £1440 sitting at 160bhp, apparently pulls to 60 in 6.8 seconds which is pretty quick.
Mazda RX8s 230hp sub 6 second. Plenty around for less then a grand if you can live with repair costs.
Lexus GS350 or I even found a GS430 with the 4.3lt V8 for £1595 at dealer. May be able to talk him down to £1500. Again 6 second luxury car
I have a trust fund set up for my boy, with the idea of paying uni fees or house deposit. Now I think it might be needed to insure him on his first car
My Chloe whose 19 has just passed her test. We got her a 2007 Clio Dynamic 1.4 from a family friend, 30000 miles and immaculate. For a 90hp 1.4 engine top of the range car she is paying £540 Full comp insurance through Hastings which I thought was pretty good. We do have a garage and live in the country which probably helps.
