Hi Tony,
I ran the RB6 most of this season and all of last season, I loved the car and had very little breakages in that time, a nice solid car and I have seen some secondhand bargains on oOple recently. As previously said there is quite a few different cars running at Bury and if you ask 10 different people what to get your probably going to get 10 different answers.
When I got back into the game I wasn't sure what car to get and ended up getting the one I personally thought would be the best/easy for the electrics to be installed and looked the best.
Get down the track and have a look at what's racing and the one you like the look of
