Yep, I agree with toffy.
Step 1, buy a manual RWD car with LSD or weldy for less than $1500
Step 2, get some tyres
Step 3, go to a drift practice day.
Step 4, rip some skids.
Step 5, repeat step 4 until you run out of something (tyres, fuel or talent)
Keep drifting that snotter for at least 1 season. Maybe give it some love, see how you feel.
Once you've mastered that and can rip a pretty good skid, save up and buy a 2nd hand car that's already proven, you see lots of drift cars for sale for less than $15k that are pretty epic. And I can guarentee you'll get more bang for buck getting a $10-15k drift car than spending $15k on your snotter. Plus you can then lend your snotter to a mate and share the drifting love
If I had to do it again that's what I'd do. I spent too much dosh on my car straight up, now I'm to chicken to point it at the wall or do massive entrys.
