new to off road, advice please!

[catman79]

hi guys,
ive been running touring cars for several years, i now plan to also get myself an off road set up for the coming summer, probably to be raced at ipswich and colchester mainly. looking for a new 4wd buggy, just wondered what peoples recomendations are? cost isnt too much of an issue, have around £300 ish to spend on the car itself.
thanks in advance.
