The Type 14 Elite was a two seat coupe that was considered an ultra-light car. It had the 1.2 liter Coventry Climax I4 engine, which was all aluminum and made 75 horsepower. That may sound weak, but remember this is a very light car, so it actually was able to achieve performance in line with sports cars of that time. This car won its class at Le Mans for 6 consecutive years. The drag coefficient was also a factor in this cars road racing performance. It was just .29, which would be a great number even for a modern car.
The second Elite was a larger saloon car. It had a front engine and rear wheel drive, and it had the steel backbone chassis that was derived from the Elan. With a 907 4 valve DOHC 4 cylinder aluminum engine and 4 wheel independent suspension, the performance numbers on the Elite II were not bad. Automatic transmission was made available after 1976.
These cars can be found out there on the used market, although not usually in the places you would look for used cars. You can find them listed on eBay, along with a large variety of Lotus parts.
