Heavily engineered. Will literally go through anything, as long as you aren’t in a hurry. Dropped a valve three years ago, my fault, didn‘t change the exhaust valve for one of club manufacture. Even though minimal damage done still cost me £200 to fix barrel & piston head. This Scottish holiday, see web page (URL above), was a lot of fun and you see so much more of the countryside at 30mph than you do at 70. Very relaxing, but a challenge for the car, all the same. Final day’s drive home was 360 miles in 12 hours, a bit tiring but satisfying to reach the end.
