Echoing what Leon said re not putting down money up front on a lease (called Cap Cost Reduction). Basically you have the option to pay $2000 across 24 monthly payments of $83 per month, or pay it all on day one (no benefit or discount in paying up front). Also if you have an accident and write off the car in month 2 of 24 you don't get anything back from the $2000 you paid up front from your insurance whereas if you had paid that $2000 over the 24 months you would be better off. Of course sometimes one is aiming to stay below a $ amount per month (to keep spouse happy or whatever) so a small Cap Cost Reduction might be ok (but $2k on a $53k vehicle is way too much).
When leasing you are paying for two things: depreciation on the vehicle over 24/36/39 months and the interest on borrowed money to the bank (who actually owns the vehicle during your lease). The current Money Factor (MF) for Stelvio Ti Sport for 24 months is 0.00008 (*2400 = 0.192% interest so very low and under $10 per month in your case - and you can't effect this number as it is set by the bank). The Residual Value (RV) is also set by the bank but assumes MSRP ($53k in your case) and on 24 month/10k miles per year is currently 61% - so your vehicle will depreciate 39% over the 24 months and be worth $32330 to the bank at the end. If you managed to negotiate your sale price of the vehicle from $53k to, say, $50k (called the Cap Cost) and then applied $4000 of rebates and incentives (set by Alfa Romeo, varies by region) to that negotiated price to get to $46k then you are only paying for $14k depreciation over 24 months = about $580 per month. Add the $2000 in up front Cap Cost Reduction you mentioned and the $580 drops by about $83 per month to $497.
I made up the above numbers but hopefully you get the gist of it. And you may have noticed that everything above is fixed by the bank or by Alfa Romeo (MF, RV, MSRP, Rebates etc) and the only thing you can control is the negotiated sales price - just like if you were buying the car vs leasing it. Focus on getting a good sale price - below invoice is easily possible for the Stelvio tight now.
Some unscrupulous dealerships will lie to you about the Money Factor (interest rate) and say you are getting a great deal at 2% (vs the actual 0.192% set by the bank) or will muddle other numbers, or keep incentives for themselves, or hide a bunch of stuff in inflated inception costs (registration, doc fees etc) - just walk away from any dealership not willing to disclose the actual numbers they are using.
I use Edmunds for MF and RV info for leases:

This is a good lease calculator:

Hope this helps. Having said all the above I think your lease deal is not too bad - I ran some reverse calculations and am guessing your final price including rebates is about $45,700 so over $7k off MSRP. Feel free to PM me if you have any questions - I've leased my last 15 vehicles and enjoy discussing the process.
