yeah you should find something you would be happy with for 13k. a series 2 might be a little more. i got my series 1 95 for 11, so you just got to be lucky and do some hardcore searching theres a "plethera" of parts people trade on here, plus shops, mags, ebay.. so you should be sweet. i personally pay 1400 for insurance, being male, having a turbo, and being under 25, you definetly have the odds against you with insurance.
good luck with the hunting
