I had a BRG MGB. Cannot remember the year. I bought it and within days realized I was getting 200 miles to a quart of oil. Only after purchase did I put my finger in the exhaust pipe and finger was sticky with oil. Where were you guys back in the 70's? PPI? No. Duh....
I did not find it an exciting driver. Pretty bland. Certainly no Porsche. And not as much fun as a Triumph TR3. If you can find a rust free one it might be okay. Whenever I see one running I go up to the driver and congratulate him on his commitment to the marque.
The neatest setup I have seen recently in an old British car was a Triumph Spitfire with a V8 shoehorned in it. I tried to flag it down but was too fast. If it was the original 4 cylinder I could have caught up with it.
