Well, I would sell it and find a 4 seater. Can haul a lot more stuff. The SxS market is shit. For what you will dump into yours you can probably get something better suited to your needs for less.
You very first sentence says the car is not used much. Why bother throwing money at it unless you plan to start using it more. It's managed to survive this long without upgrades. Leave it alone and save your money for the Funco.
Be sure to tell Anthony you want the heavy duty ramp door. I have had my ramp door replaced already as there was no beam where a rails tires line up and the wood breaks down from loading. Great trailers otherwise.
It's funny to me how pussified the sport has become if that pass is considered bad. Damon Bradshaw or Chicken would be broke with today's racing standard.
I dropped my car off at the Wright Gearbox today so I won't be able to meet up. However, I stopped by Funco today to pick up a buddies car and got a chance to check out yours. I think you're going to be pretty stoked when you see it in person. Enjoy and hope the shake down run goes smoothly.
