|Comments:||Most of the modifications to this car were made by the previous owner,
Dan Tyler of San Jose, CA. I have been sorting the car out and making minor
changes to suit me since purchasing it 6 weeks ago.
New burled ash dashboard (installed January '08) with glove box and new gauges.
The dash as received when I bought the car...
New leather upholstery and trim from Moss Motors...
...but the Triumph seats weren't comfortable enough, so
Mazda Miata (MX-5) seats were installed in late 2008.
The rare surrey option provides more shelter than other convertible top designs.
All of the car's sheetmetal is original and rust free!
The surrey hard top was bare aluminum when I purchased the car, but it's now been
painted body color and trimmed with new headliner fabric to match the interior.
