Yokomo MR4 BC 2 Special

[pumpkinfish]

My first post here, I love the site! Great reviews and information.
I do need an opinion from you experienced 4WD racers. Is it worth racing my BC Special or getting a new buggy? The 4WD scene with 19t motor is picking up at my local track here in America and this is what I have to go up against the Losi's. My main problem is I have no spares for the car and it is box stock. I would assume for the typical US supercross style tracks I would need the slipper, correct? So factoring in the usual spares and slipper, I am up around the cost of the Kyosho Lazer ZX-5. So I am wrestling with the choice of new car or buy spares.

What is the more intelligent choice? I have never raced the BC Special so I have no clue how durable it is under race conditions. I have only run on tracks by myself at a leisurely pace. I'd hate to race it and be fixing it after every race. I have been down that road before...lol!

Thanks for any insight that you guys can provide.
