Executive Car for Dad

I have a lovely job in hand to find the next car for my dad , but the only irritating factor are the terms and conditions of his.. Firstly let me brief you about our current car, its a 4 and a half year old Toyota Camry chauffeur driven 1,15,000 kms done. His daily journey to office and back is about 90-100 kms.
Traffic within mumbai , but once out of mumbai smooth n fast on the highways.

He never drives himself , we have the same driver for the last 28 years!!

His long list of Terms and conditions :-
1. He wants to move on to European cars
2. Cars which are low profile ( Lay man should not know the real cost )
3. Good mileage
4. Good suspensions
5. Diesel preferred
6. Good after sales
7. 5 seater

Budget is anywhere between 25-50 Lac

A lil help please:
