2 x SL129 – which has more potential?

I am still thinking of buying a nice R129 – had a SL280 (1996 year of construction)…he would be a pure hobby / weekend car for nice days and no everyday use. I have to say that I (still) live in Dubai, and the SL in any case for a (very) long time – so also again in D, should stay in the fleet. Here are now two available, which I like both quite well – which is probably the better choice here (same condition and condition). d same purchase price accepted): A) SL320 from 1998 (still with the M104 R6 engine) – 126.000km, very well maintained with documents including purchase invoice etc. – smoky metallic, inside safran/java (264A) with dark brown softtop – panoramic roof, xenon – otherwise no superior equipment B) SL500 from 2001 (one of the last, more details – whether special model still unclear) – 105,000km – silver metallic, inside gray seats and cockpit, cover rack, overroll jacks are red / red – AMG package, X enon – other equipment unknown (I don’t have the VIN yet) The 500’s naturally appeals to engine technology, whereby I think the 320 is sufficient (it’s either way not a sports car), color combinations please me both, the panoramic roof is a big plus point from the first, the AMG package a smaller plus point from the second … which therefore take into the short choice?!
