You are right about the high prices. Digital meter is quite rare now a days that's why costly. Here it cost about Rs.12K if available + Electrician charges are about Rs.2K since wiring needs to be rerouted. Also you cannot blindly give it to any electrician as it needs expertise otherwise it is too risky if just one wire is wrongly connected.
Cielo steering wheel has two variations, one is three spoke and the other one is four spoke with SRS written in the center. The latter one is little costly. Regarding power window machines, if they are original with switches & wiring, the price is justified.
