The E240-2.6 W211 in Thailand (assembled in Thailand) comes with a 3-year parts and labor warranty when buying from an authorized Mercedes Benz dealer. Nevertheless, the warranty is void if an owner make any modifications to his/her car. This is quite frustrating for owners with a lead foot. The car's suspension is adequate for average speed, but when pushed close to its limit, the suspension as well as the 16 inch wheels and tires cannot cope with harsh driving. The modifications can be made to the car however, but only AMG products are allowed and must be bought from the dealer. Therefore, upgrading wheels and tires, or the suspension, that are not AMGs will void the warranty. Usually, any AMG products sold by the dealers are more expensive than acquiring them from gray-market dealers.
The sound system is very good for a factory system.
The space for the rear passengers is tighter than the predecessor, the W210, nevertheless quite roomy and comfortable.
On smooth roads, the car rides very smoothly.
The 4th gear red-lines to 5th around 200 km/h. Once the 5th is engaged, torque is very low and drivers are discouraged from going any faster. At 200 km/h however, the car is amazingly stable for a non-performance sedan.
The interior design is world-class. smooth lines everywhere.
I find the tiptronic gearing awkward. Instead of the logical ups and downs (plus and minus), it is left for downshifts, and right for upshifts. With the mileage 11000 kilometers under the foot, it still feels awkward.
When trouble comes, I would rather be driving a W124, where not everything is electrical. With the W211, it is almost all electrical, which can be quite expensive to fix.
In conclusion, this W211 is far better in all aspects (except repair costs) than the W210 (E230) and the W124 (E280). A good all-around car, with enough power for an average driver. For fast drivers, go for the E500 or the E55 AMG. Otherwise, the E220 or 270 CDi is also a very good choice.
