I go through a phase regularly where I look at MGs, Spitfires, Fiat 124s, etc. thinking that i need a "foreign" car in my collection. Everyone I have talked to has warned me about getting an MG saying that while they do handle, they are not fast and not real roomy. My desire is a drop top type vehicle and I look at a variety. After awhile I default to the fact that I have 2 Harleys and they suffice as a convertible..
I do like the Interceptor but they are hard to come up. If you really want to talk to someone who knows them, contact Bruce at F&B Fuel Injection (makes the EFI 6 pack), he has one and in fact it was the impetus for him developing the EFI 6 pack. His website is "under construction" but there is a contact me button at the bottom of the page.
