mk4/mk5 fiesta 1.25
mk1/mk2 fiesta 950 or 1100
pug 106 or saxo

just go whichevers cheapest, my mate has not long passed his test and has got a mk1 fiesta 950 with all the xr2 kit, alloy wheels, sound system, alarm, immobiliser the lot... rang footman james and they quoted him £1013 or it would be £1200ish with a 1300 in it
only thing is with classic car insurance, you wont get any NCB but if your with them for say 4 years and you dont have a claim, then if you was to change to direct line etc then footman james will let them know that you havent claimed, and its up to the new insurers whether to reduce your price or not

ive got a mk1 fez 1100, boggo standard except sound system, my quote should be around the grand - £1100 mark

my sister has been driving for a year in a mk5 1.25 fiesta, im insured on it on my provisional and they are nippy little bastards for the engine size e.g. im doing driving lessons in a 1.2 fiat 500... the fiesta is fucking rapid compared to the fiat even though its 10 years older. Its even easier to drive and actually drives nicer than the fiat
