The TR and the MG are totally different cars. The TR4A irs was more of a beast.I had the engine on steroids and all the goodies. Good part springs, adjustable rear brackets,TR6 Front bar,Big bore kit,shaved head,over size intake valves,cam from Ken Gillander,O/D,Infinaty rear diff, SU carbs,lightened flywheel and then there was the body.ARE silverstones,Surrey top,Repro console from Harry Beaker and a group 44 silver stripe. Can you tell i miss that car? The MG's are a bit more stable on the road and tighter. The TR had GRUNT and a look like no other car out there. They each have there own charm and MG and TR people are the best!My TR4a has been gone for less the 2 years now. Maybe another one will follow me home one day. Thanks for letting me share my experience, Bob
