Hi Pete.
First of all congrats on having your car entered to begin with.
Don't get caught up in the misconception that the most spent reveals the best results - I have seen a number of high $$ cars fall way short of where I thought they should have been. You're obviously a person who knows about your car and havn't paid for someone to do the work who "thinks" they know about a particular car. There is a BIG difference!
I'm sure the RS will give the big boys a run for their money and best of luck!
