ai do wat gn3dr says not so much the expence its the bloody shell prep thats the longest and surprisingly expensive only when you look back and add up all the shit you spend money for shell prep youll no lol, if i had to start my car again id would still build from scratch but buy a prepared shell from a spelist what you planning on????
Would definately go along with buying secondhand rather than new on cost grounds. 5000euro's should get you a decent car to have a good bit of reliable fun in, if not bought here then across the water. Motoring news classifieds usually has a few in it each week.
NDE Motorsport supply a lot of reliable cars to those starting to rally. There are a couple of MKII escorts and a few 205s available at the minute. If you are interested U2U me and I can forward you some details.
