73800kms update:
In recent times, I noticed the car had a tendency to vibrate at certain speeds. I thought it could be a bad wheel and got the car balanced at Madhus. While doing the balancing, the operator did tell me about the wheels being slightly bent but he'll try to balance it nevertheless. Post that, the vibrations shifted to another speed range and it was a bit nervous to drive the the car that way. I had two thoughts, whether to replace the alloy with the same model or whether to go for a brand new set. I did enquire in a couple of places and also consulted with Vicky. He recommended me to go for a brand new set instead as the existing alloys were from a model of Mercedes E class that is no longer in production.
I saw the OZ Leggara HLT on Vicky's Laura sometime back and was impressed with its simple and elegant design. After scouting the OZ racing website for a few days, I narrowed on the OZ Leggera HLT 17" model. Confirmation bias perhaps. In between, Vicky did send me pics of 18" alloys as well, but after thinking about our road conditions, I decided against it. Paid up an advance and the waited for the alloys to reach me.
The next call was to Nikhil, to help narrow down the tyre choice. I told him I was running the Continental Sport Contact 5 currently. He recommended me to go for the Michelin Pilot Sport 4 as a replacement option. His team called me up to apprise me of the stock condition and I paid an advance to hold the tyres for me.
Yesterday, I got a call from Vicky stating the alloys have reached him and I can go pick it up. He was kind enough to drop it at Vaishak's place and I went there to pick it up. Also got to meet his "Monster 530d" - very subtle and unassuming from the outside, but packs a solid wallop.
I had take the alloys and rush to Madhus at Wilson Garden as it was already 5:30 in the evening, they close by 7pm. Loaded the alloys in the boot - Vicky was telling me, I couldn't even fit more than two alloys in my boot, whereas in yours we can even load all 4. Practicality. I called up the person in charge at Wilson Garden and told him to get the tyres ready for the install.
The best part about visiting Madhus is that everyone remembers you and greets you with a warm smile. Very courteous staff and very good at what they do. I was the last customer for the day and that proved to be a blessing as everyone came about to help with the install. Attaching some pics from the install.

Road force summary
Huge thanks to the staff of Madhus in the install, everything was checked and double checked. It was almost closing time, yet they ensured it was done properly. While mounting the tyres on the alloys, one of the tyres hadn't seated properly and hence was showing hotspots in the rig. It was marked and was unseated and re-seated and refilled with nitrogen. Post that, the hotspot went away and it was back to good.
After the install, I was driving back home and wanted to check whether any vibration symptoms from before existed. The roads were congested and traffic was a bit thick, so couldn't really do any assessment. I hope to check that once I get a stretch of empty road. I'm now extra careful while going over bad patches - new alloys, new alloys says the mind.
Overall, I'm very happy with the choice of alloys. Looks subtle and elegant and helps maintain that sleeper look.
