Ill probably be slated for this but if you like messing with your cars (properly not like chav), then the fiesta st is very underrated.
I have started getting underway with mine, power is easily amped up to around 180bhp-200bhp with varying torque with basic mods (FR cams, map and breathing) because of restrictive oem parts, a lot of weight can be taken out of them, and they handle awesome on track standard, let alone on good shocks like GAZ or bilstein, and with an easy sub £300 brake upgrade from the MK1 focus RS.
Worth a look in as insurers like Greenlight wont charge any extra for any of those mods bar a £25 admin fee when its all updated, so your paying 150bhp insurance for a 200bhp car.
If you wanted more power, buy a cheaper one and pay around £3k for a supercharger from someone like Jam-Sport with the potential of circa 270-370bhp depending on other mods.
Clio is a brilliant little car as well, and my mate has had one for almost two years with no trouble, early cambelt change though at around 35k iirc. Fiesta is chain driven so no worries here.
EDIT: can get these at around £3500k up to 8k for a newer one, and the i4 engine is built like a rock so dont worry about mileage.
