HELP!!
 

hi i brought a wrx prodrive 03 nearly two weeks ago and thought it was great but then only 2 days after having it i heard a really strange noise which u may remember me askin u about well i took it back to the garage where i brought it from as it is still under warranty and they phoned me today and told me that its the crank shaft there garage is fully booked and they recon its gonna cost £2500(covered by them of course lol) and i wont get it back till bout 20th of feb what do u think i should do? should i just let them fix it and wait till its done or shall i tell them to not bother get my money back and go buy another 1 pls help me!!
p.s once the crank shaft is replaced will the engine be ok or will i have more probs with it if tht makes sence
thanks ben
