New Triumph TR-4A is one sports car that won't shake your fillings loose. New independent rear suspension* smooths the bumps. It also prevents rear-end rhumbas. Even if you hit cobblestones at 100 mph. (Here's another eye-opener. No other sports car manufacturer offers a car with IRS for less than $4000. That's almost 40% higher than TR-4A.) More TR-4A innovations: deep-cushioned bucket seats and easy-up, easy-down convertible top. Of course, it retains those features that made the TR-4 the SCCA National Class Champion for three straight years. Such as four forward synchromesh gears. Rack-and-pinion steering. Low center of gravity. Enormous disc brakes. (How about the availability of Triumph services? No problem. Parts are available through a nationwide network of factory warehouses, distributors and dealers.) There's something else about the new TR-4A that won't shake you up. That's the price. $2899**. *Optional at extra cost. **Suggested retail price POE plus state and/or local taxes. Slightly higher in West. SCCA-approved competition equipment available. Look for dealer in Yellow Pages. Overseas delivery available. Standard-Triumph Motor Co., Inc., 575 Madison Ave., N.Y., N.Y. 10022.
