Sure, but the MKV and especially the 2-door DHC with the hood down is not very different as an experience from the XK’s. Although the chassis again is the same on the MKV and MKVII the later feels (and probably is) much heavier than a MKV DHC.
The original point was and is, that for many customers of Jaguar, especially overseas like my car was sold new by C. Hornburg in Hollywood, LA, if they were buying a ”Jaguar convertible” it made not much difference if it was a MKIV or MKV DHC, or later the XK120 or XK140 DHC, it was a Jaguar convertible. The XK140 even became available with an automatic gearbox.
I have driven many XK’s and also a MKVII and a MKIX and despite the more powerful XK engine, IMO my MKV DHC with the hood down looks and feels more like the XK’s than the Saloons.
That’s why I was trying to point out that Jaguar had had customers for a more luxurious convertible, aka a drophead, they had made some from 1935 to 1940 and then again from 1946 to 1951,
Also the SS1 vs SS90 / SS100, the very first SS90 even had an SS1 chassis number (and still has) as it is what the first sports car was built around.
When the MKV and XK120 were introduced in late 1948 they were designed and built by the same people, mostly from the same parts, on the same assembly line etc.
I have had the MKV DHC for almost 19 years. The XK120 is much closer to it in design and driving experience than the XK150 is to the E-type.
Also if you look side by side, an XK120 DHC (or a 140) and a MKV DHC, both with steel wheels, spats, hubcaps etc and take a look inside, they are, very, very similar. The MKV is just a bit taller, longer and heavier, but no-where nearly as much as a MKVII-MKIX. The wheelbase on them is the same, but the MKV body is much smaller and lighter than the later Saloons, and the drophead even more so.
Have you driven a MKV DHC in good nick with the hood down? 70-75mph effortlessly.
Ps. Of the XK’s I have driven a few, an 1952 old race car on tight curvy country roads, and a few XK140 and XK150 FHC’s, well tuned ones.
