First car I ever drove in LFS was the XRT. After they took that out of the demo I drove nothing but the FBM on BL1.
When I got my licence I took the LX4 on Westhill international, thats mostly what I've been doing since then, other than driving the MRT on the same track.
I've only had my licence for a fue weeks now, and I've always wanted to drive the LX4, so as soon as I got my licence it was like "MUST DRIVE LX4!"
