Probably some other stuff I've forgotten about

An overcast Friday in my area today and I had seen an i8 and a Lancer Evolution VIII MR.

Saturday:

Existing spots from several days ago will not be included, so I just posted new ones.

- Lamborghini Murcielago LP640 (the same one I saw in PIK Avenue months ago)
- Ferrari F430 (not really a miss since I also had seen the exact same one months ago)
- Porsche 911 Carrera S (991)
- Alfa Romeo 1750 GTV
- A Honda Civic Si Coupe (EM1), in Indonesia! For North American spotters, this might not look unusual for you, but outside the region, it was.

Sunday:

Although I was not really planning into car spotting today, but I did see:

- Aston Martin DBS Superleggera
- Lamborghini Gallardo LP550-2
- Porsche 911 GT3 (991)
- Porsche 911 Carrera GTS (991)
- PorscHE 911 Cabriolet (964)
- Maserati Quattroporte
- Audi RS5 B9
- BMW M4
- BMW M3 F80

Missed:

This Toyota Supra A80:

Quick question: What does "missed" mean? I thought it meant that you didn't get a shot of the car but you posted a pic of that MK4 so now I'm confused.

Missed = I saw the car but I failed to get a pic of it.

I posted a picture of the said car because I had seen (spotted) the exact car previously. Basically, I saw that same car but in a different place.

Monday:

- Missed a Nissan GT-R that I had spotted previously
- BMW Z4 G29
- BMW M2 (missed)

How many of the MSO 600LT were made?

Thanks for the clarification.

Not registering much activity today, but indeed I see these on Friday:

- Lamborghini Urus
- Nissan 350Z
- BMW M2
- Subaru Liberty Wagon

Saturday:

- Maserati Quatroporte Sport GT S
- Rolls-Royce Ghost (blurry shot)
- BMW M2 Competition

Sunday:

Wow, winter's kicking in...

There's no set production numbers because any car can be MSO'd while it's being built, and McLaren didn't limit how many could be MSO'd.
