Yes, the Dyna Tech has XT, the Excel had used Supra bits IIRC.
The capri comaprison comes from experience. I have owned a Capri, and an XJ-S (badly built V12 Capri) and nearly bought an Excel (glued together Capri) and have been fortunate enough to drive countless V8 Aston's including a handful of Virage's and a V8 Vantage (twin supercharged 1994-> car). They are just dirty great alloy Capri's!
Before I get lynched... Underbraked, over powered, suffer from transmission and axle wind up, four seat's and wildly fun in the right hands. Wildly dangerous in the wrong ones mind. Both cars meet the criteria!
Oh I also had a BMW 635CSi (german overly complex Capri!!)
And a Nissan 200SX S13 (Japanese Capri)
Somerset, like 'Heartbeat' with newer cars!
