As I noted in other comments, soon after purchase I provided it to our German car specialty mechanic shop for a sort-out inspection and I did not receive any comments about idle speed. Thanks.August 25th, 2025 at 2:56pm EST$2,000 bid placed by @Babyhani1August 25th, 2025 at 2:56pm EST$1,250 bid placed by @SellCLEAugust 25th, 2025 at 2:37pm EST$1,000 bid placed by @Babyhani1August 25th, 2025 at 2:18pm ESTEurocayman (0) 0@Seller do you know why it idles so high even when the engine is warmed up? 1100 rpm idle seems very high.August 23rd, 2025 at 10:27am EST$750 bid placed by @SellCLEAugust 22nd, 2025 at 8:25pm ESTjwjohnson86 (0) Seller 0Correct, the rear window sunshade does not work. I did not do any timing system work and all invoices I received from the original owner are entered on my spreadsheet. All power windows and central vacuum locks operate.August 22nd, 2025 at 4:53pm ESTottobenz (11) 0@rezwiththebenz while not speaking on behalf of the seller, I already asked that question and he already responded. Based on the invoices, he has "no knowledge of any prior timing system repairs"August 22nd, 2025 at 4:13pm EST$500 bid placed by @RezwiththebenzAugust 22nd, 2025 at 4:12pm ESTRezwiththebenz (0) 0I also want to chime in, and of the major timing components done?August 21st, 2025 at 5:41pm ESTjwjohnson86 (0) Seller 0Thank you for your compliments. The octogenarian original owner (who bought it for his wife) apologized that the sunshade no longer worked. I have not attempted to sort through that. All other power accessories work including the antenna; I purchased and installed a new rubber grommet at the antenna base. You will see screw holes on the driver door card where an aftermarket cup holder was mounted but the aged plastic crumbled. The passenger door cupholder still is there. As for service I abstracted all the invoices I received from the original owner into the spread sheet, I have no knowledge of any prior timing system repairs.August 21st, 2025 at 5:33pm ESTottobenz (11) 0very nice looking 420SEL, repainted in Midnight blue, which is such a classic Mercedes paint color. Interestingly optioned with front heated seats and power rear sunshade. I gotta ask, does that rear sunshade work? there were no photos of it in the up position, and I understand they are notoriously unreliable. Can you indicate anything that is NOT working (sunroof including pop-up feature, central lock from both front doors and trunk lock, power windows including the rear windows)? Also, reading through the extensive maintenance I don't see that the timing chain/guides/rails have ever been replaced (I ask because they are time-sensitive bits, not necessarily based on miles).August 21st, 2025 at 2:06pm EST$250 bid placed by @SellCLE
