i was in exact same position when i bought my ek4, the amount of time, money spent on achieving results etc, money lost in mistakes so having to do things again etc (learning) as cost me a fortune but guess part of it was the fun factor
now the simplest way to achieve what your after from your car is wait, save and buy already modded car or somethin like ek9 and sell yours (i didnt do this as didnt realise what id go through)
may sound harsh but being 100% honest as ive been there, i do and dont regret it but when i look back at money ive spent it hits now real bad with whole economic climate when i could have done with that money
