Maybe you should be certain of what you want before you consider buying and modifying them...

Perhaps go to a car show or drag race near by and see some of these cars actually go before committing yourself to them.

You seem to have gone through lots of changes of heart in the last few weeks. Wha would have happened if you had actually bought what you wanted back in the first week? would you have regretted it?

May want to put some more thought into it...
